Myainvention relates to running gear for power-driven vehicles having aplurality of driving axles, and more specifically it relates to a novelt pe" of mechanism for interconnecting the chassis with the several axlehousings of vehicles of the character designated.

This'ap'plication is .adivision of my co-l pending application SerialNo. 508,844'filed October19, .1921, which matured into Patent No.1,565,527, on December 15, 1925-.

' The object of my present invention consists in prov-idin a vehlclerunmng gear of the character afiove described having an unproved-formof. couplingbetween the axle as to aid in. the transmission'of thedriving and braking forcesto the vehicle wheels, and

to "relieve substantially the springs, by which the'chassis isyieldinglyi 0 connected to. and supported from the housings, from all torq'tilieand the driving and braking stresses. T ecouplings form ng the subjectmatter of this divisional application 'comprise radius rods or barswhich serve to retain the housings in the proper relative positions withrespect to the chassisiwithout re-' strictingthe relative movementsofthe housing ends asthe vehicle passes over uneven surfaces. y

For a better understanding of my inven-; tion, reference maynow be hadto the accomt 'panying drawings, of which:

, V Fig. 1 is a vert cal sectional view of a truck embodied therein and.r Fig. 2 is-adetail of thetruckshown in Fig. 1, illustrating one form ofconnection between the springends f and the axlehofisihgs andtherelation of the support ng springs.

T, e housings 2 are connected totbe frame orchassis 3 b means supporting housing, so as to. swin I ordriving-elflljieiit of a vehicleofthe char- .35 acter abovedesci'ibedhaving my invention. a resilient, which resu the members which formthesockets of the ball andsocket joints upon7coil springs ori in my"sectional view of a portion drivin'g .axles 1 are each en-- closedwithin axle-housin' 2 which are free-- ency'to rotate may be'resisted,without sacrificing the freedom of movement of the-in dlvidualhOIISIIlgS, by means of torque neutrahzing mechamsm, various forms ofwhich are fully illustrated andv described in my' previously mentioned'co pending appliow tion. The form of torque neutralizing mechanismtherein disclosed, comprises torque bars 8 which are arranged in suchrelation that the v torque effects from one axle are directed to opposethe torque effects of'the other. To this end the bars 8 are disposedinsuperposed. parallelrelationship, and are arranged longitudmally of therunning gear, preferably in the median plane thereof. Each torque barSis pivotally connected, as indicated at '9,to

a lugor arm 10, extendingbfrom its associated with respect thereto.he'torque arms 8 are preferably connected to each other by means ofVertically disposed links or shackles 11. The attachment between thearms 8 and, the

shackles; 11 is preferably effected through interposed universal joints12015 the ball and sockettype. .The torque neutralizing interconnectionsshould'preferably be somewhat t is effected by mounting other resilientmembers, as disclosed co-pending application.

My improved coupling. mechanism is adapted for use with a form ofrunning gear embodying, asillustrated in Fig. 1, a. drive a out avertical axis 'ls shaft 13, which may be'driven from any -appropriatesource of power, (not shown) 1 and worm and worm-wheel transmissiongearing mechanism. for transmitting energy from the dr r as it .3 to. two w eel-dar g -3 .frame or chassis 3. The radius rod 18 is-conaxles 1.These transmission mechanisms enclosed wlthm gear 'cases 14 suppglrtedby. I their associated axle housings 2. e

gearing mechanism associated with the leading 5 driving axle isconnected tothe worm of the trailing d'rivin axle by means of a shaft15, 1 preferably ren ered articulated by the inclusion of universaljoints 17 and rendered extensible by means of splined telescoping con-.

nections 1 6, as shown. Driving gear of this character is more fullyshownand described in the aforementionedprior application and, inasmuchas the drivin mechanism forms no part of the invention erein claimed, ithas 1 not been described in detail herein.

In certain forms of m invention substantially all of the acceleratingand decelerating forces are transmitted from the axle housings to theframe or chassis'through the 20 springs which form a yielding connectionbetween the several housin s, and between'each of the housings and the cassis. In the modification herein specificall disclosed, thetwo housin sare coupled to t e chassis by means 2 in addition to the springs,and'the' connecnected to the heading housing 2 by means'bf a universaljoint 23 and to the trailing housing 2 by a similar joi'nt24. In likemanner the rod 19 isconnected to the leading housin 2 40 by a universaljoint 22 and to the arm 20 y bars. I

- means of a umversal joint 21L .The" radius rods are preferablyinvariable in length so as to serve as thrust rods as well as draw Inorder to provide for the spreading of the spring ends as the. spring isflexed, {notwithstanding the restrictions in the movie- I ments of theaxle housings owing to their in-- g dependent'couplin with the chassisbymeans of the rods 18 an 5 e p g stood that the rods 18 and .19are.disposcd along substantially the center line of the houstlfereof, itwill be apparent 19, the spring ends are slidably. connected to thehousings by means of socket or sleeve members 25 which prevent relativelateral or vertical movement but pere 'mit of a; limited longitudinalmovement of ends therein.
